FIELD OF THE INVENTION

The invention relates to cosmetic compositions comprising a combinationof non-emulsifying and emulsifying crosslinked siloxane elastomers.

BACKGROUND OF THE INVENTION

Emollients including organic esters and hydrocarbons, especiallypetrolatum, have long been used medicinally as skin conditioning agents.These substances are second only to water as moisturizing ingredients ofchoice. They function primarily as an occlusive barrier. The watercontent of the outer layers of human skin stratum corneum is acontrolling factor in the appearance of dry skin symptoms. When thestratum corneum contains an adequate amount of water within the range often to twenty percent, the skin remains flexible. However, when thewater content falls below ten percent the stratum corneum often becomesbrittle and rough and can exhibit scaling and cracking.

The stratum corneum receives its water from the deep layers of theepidermis by diffusion or when it is brought into direct contact withwater. The diffusion process is controlled by the water content of theskin as well as the concentration gradient. In a very dry environment,the water loss from the external skin layers can be significant andoften exceeds the rate of replacement by diffusion. An occlusive orsemi-occlusive barrier substance placed on the surface of the skin actsto retard water loss to the environment. It also allows the skin surfaceto rehydrate via a diffusion mechanism.

While there are many effective and economical skin conditioning agents,they nevertheless suffer from certain disadvantages.

Often the emollient types are delivered as water-in-oil emulsions. It isdifficult to attain the critical formula balance between oil and waterphases to an extent sufficient to ensure long term storage stability.One part of this critical balance is the internal phase volume. Acritical volume must be obtained to maximize the chemical and physicalinteractions, which produce and stabilize the system. If this criticalvolume is not balanced properly the product may suffer from viscositychange and eventual phase separation. Usually the optimum volume isquite large which limits the external phase volume size, and gives thesystem a draggy unfavorable slow break attribute. This critical internalphase volume restriction can reduce functionality and add unfavorablefeel characteristics.

New systems are needed to carry relatively high levels of aqueous basedmoisturizing ingredients (e.g. glycerin).

Accordingly, one aspect of the present invention is to provide cosmeticcompositions, which provide improved skin-feel properties.

Another aspect of the present invention is to provide a skin treatmentcomposition, which has stability against phase separation even underfreeze/thaw cycling.

Still another aspect of the present invention is to provide a skintreatment composition, which achieves a smooth non-draggy rub-in uponinitial application to the skin.

These and other aspects of the present invention will become morereadily apparent from consideration of the following summary anddetailed description.

Crosslinked Siloxane Elastomer

An essential component of the present invention is a crosslinkedorganopolysiloxane elastomer. No specific restriction exists as to thetype of curable organopolysiloxane composition, which can serve as thestarting material for the crosslinked organopolysiloxane elastomer.Examples in this respect are addition reaction-curing organopolysiloxanecompositions which cure under platinum metal catalysis by the additionreaction between SiH-containing diorganopolysiloxane andorganopolysiloxane having silicon-bonded vinyl groups;condensation-curing organopolysiloxane compositions which cure in thepresence of an organotin compound by a dehydrogenation reaction betweenhydroxyl-terminated diorganopolysiloxane and SiH-containingdiorganopolysiloxane; condensation-curing organopolysiloxanecompositions which cure in the presence of an organotin compound or atitanate ester, by a condensation reaction between anhydroxyl-terminated diorganopolysiloxane and a hydrolyzable organosilane(this condensation reaction is exemplified by dehydration,alcohol-liberating, oxime-liberating, amine-liberating,amide-liberating, carboxyl-liberating, and ketone-liberating reactions);peroxide-curing organopolysiloxane compositions which thermally cure inthe presence of an organoperoxide catalyst; and organopolysiloxanecompositions which are cured by high-energy radiation, such as bygamma-rays, ultraviolet radiation, or electron beams.

Addition reaction-curing organopolysiloxane compositions are preferredfor their rapid curing rates and excellent uniformity of curing. Aparticularly preferred addition reaction-curing organopolysiloxanecomposition is prepared from:

(A) an organopolysiloxane having at least 2 lower alkenyl groups in eachmolecule;

(B) an organopolysiloxane having at least 2 silicon-bonded hydrogenatoms in each molecule; and

(C) a platinum-type catalyst.

With regard to the above, component (A) is the basic component of thesilicone elastomer-generating organopolysiloxane, and curing proceeds bythe addition reaction of this component with component (B) undercatalysis by component (C). This component (A) must contain at least 2silicon-bonded lower alkenyl groups in each molecule; an excellent curedproduct will not be obtained at fewer than two lower alkenyl groupsbecause a network structure will not be formed. Said lower alkenylgroups are exemplified by vinyl, allyl, and propenyl. While the loweralkenyl groups can be present at any position in the molecule, theirpresence at the molecular terminals is preferred. The molecularstructure of this component may be straight chain, branched straightchain, cyclic, or network, but a straight chain, possibly slightlybranched, is preferred. The molecular weight of the component is notspecifically restricted, and thus the viscosity may range from lowviscosity liquids to very high viscosity gums. In order for the curedproduct to be obtained in the form of the rubbery elastomer, it ispreferred that the viscosity at 25° C. be at least 100 centistokes.These organopolysiloxanes are exemplified by methylvinylsiloxanes,methylvinylsiloxane-dimethylsiloxane copolymers,dimethylvinylsiloxy-terminated dimethylpolysiloxanes,dimethylvinylsiloxy-terminated dimethylsiloxane-methylphenylsiloxanecopolymers, dimethylvinylsiloxy-terminateddimethylsiloxane-diphenylsiloxane-methylvinylsiloxane copolymers,trimethylsiloxy-terminated dimethylsiloxane-methylvinylsiloxanecopolymers, trimethylsiloxy-terminateddimethylsiloxane-methylphenylsiloxane-methylvinylsiloxane copolymers,dimethylvinylsiloxy-terminated methyl(3,3,3-trifluoropropyl)polysiloxanes, and dimethylvinylsiloxy-terminateddimethylsiloxane-methyl(3,3,-trifluoropropyl)siloxane copolymers.

Component (B) is an organopolysiloxane having at least 2 silicon-bondedhydrogen atoms in each molecule and is a crosslinker for component (A).Curing proceeds by the addition reaction of the silicon-bonded hydrogenatoms in this component with the lower alkenyl groups in component (A)under catalysis by component (C). This component (B) must contain atleast 2 silicon-bonded hydrogen atoms in each molecule in order tofunction as a crosslinker. Furthermore, the sum of the number of alkenylgroups in each molecule of component (A) and the number ofsilicon-bonded hydrogen atoms in each molecule of component (B) is to beat least 5. Values below 5 should be avoided because a network structureis then essentially not formed.

No specific restriction exists on the molecular structure of thiscomponent, and it may be any of straight chain, branch-containingstraight chain, cyclic, etc. The molecular weight of this component isnot specifically restricted, but it is preferred that the viscosity at25° C. be 1 to 50,000 centistokes in order to obtain good miscibilitywith component (A). It is preferred that this component be added in aquantity such that the molar ratio between the total quantity ofsilicon-bonded hydrogen atoms in the instant component and the totalquantity of all lower alkenyl groups in component (A) falls within therange of 1.5:1 to 20:1. It is difficult to obtain good curing propertieswhen this molar ratio falls below 0.5:1. When 20:1 is exceeded, there isa tendency for the hardness to increase to high levels when the curedproduct is heated. Furthermore, when an organosiloxane containingsubstantial alkenyl is supplementarily added for the purpose of; forexample, reinforcement, it is preferred that a supplemental addition ofthe instant SiH-containing component be made in a quantity offsettingthese alkenyl groups. This component is concretely exemplified bytrimethylsiloxy-terminated methylhydrogenpolysiloxanes,trimethylsiloxy-terminated dimethylsiloxane-methylhydrogensiloxanecopolymers, and dimethylsiloxane-methylhydrogen-siloxane cycliccopolymers.

Component (C) is a catalyst of the addition reaction of silicon-bondedhydrogen atoms and alkenyl groups, and is concretely exemplified bychloroplatinic acid, possibly dissolved in an alcohol or ketone and thissolution optionally aged, chloroplatinic acid-olefin complexes,chloroplatinic acid-alkenylsiloxane complexes, chloroplatinicacid-diketone complexes, platinum black, and carrier-supported platinum.

This component is added preferably at 0.1 to 1,000 weight parts, andmore preferably at 1 to 100 weight parts, as platinum-type metal properper 1,000,000 weight parts of the total quantity of components (A) plus(B). Other organic groups which may be bonded to silicon in theorganopolysiloxane forming the basis for the above-described curableorganopolysiloxane compositions are, for example, alkyl groups such asmethyl, ethyl, propyl, butyl, and octyl; substituted alkyl groups suchas 2-phenylethyl, 2-phenylpropyl, and 3,3,3-trifluoropropyl; aryl groupssuch as phenyl, tolyl, and xylyl; substituted aryl groups such asphenylethyl; and monovalent hydrocarbon groups substituted by, forexample, the epoxy group, the carboxylate ester group, the mercaptogroup, etc.

Examples of the production of the organopolysiloxane elastomer powderare as follows: an organopolysiloxane composition as described above(additional-curable, condensation-curable, or peroxide-curable) is mixedwith water in the presence of a surfactant (nonionic, anionic, cationic,or amphoteric), and, after mixing to homogeneity in a homomixer, colloidmill, homogenizer, propeller mixer, etc., this is cured by dischargeinto hot water (temperature at least 50° C.) and is then dried; theorganopolysiloxane composition (addition-curable, condensation-curable,or peroxide-curable) is cured by spraying it directly into a heatedcurrent; the powder is obtained by curing a radiation-curableorganopolysiloxane composition by spraying it under high energyradiation; the organopolysiloxane composition (addition-curable,condensation-curable, peroxide-curable) or high energy-curableorganopolysiloxane composition is cured, the latter by high energyradiation, and the product is then pulverized using a known pulverizersuch as, for example, a ball mill, atomizer, kneader, roll mill, etc.,to thereby form the powder. Suitable organopolysiloxane elastomerpowders include vinyl dimethicone/methicone silesquioxane crosspolymerslike Shin-Etsu's KSP-100, KSP-101, KSP-102, KSP-103, KSP-104, KSP-105,hybrid silicone powders that contain a fluoroalkyl group likeShin-Etsu's KSP-200, and hybrid silicone powders that contain a phenylgroup such as Shin-Etsu's KSP-300; and Dow Corning's DC 9506.

Preferred organopolysiloxane compositions are dimethicone/vinyldimethicone crosspolymers. Such dimethicone/vinyl dimethiconecrosspolymers are supplied by a variety of suppliers including DowCorning (DC 9040 and DC 9041), General Electric (SFE 839), Shin Etsu(KSG-15, 16, 18 [dimethicone/phenyl vinyl dimethicone crosspolymer]),Grant Industries (Gransil™ line of materials), and lauryldimethicone/vinyl dimethicone crosspolymers supplied by Shin Etsu (e.g.,KSG-31, KSG-32, KSG-41, KSG-42, KSG-43, and KSG-44). Cross-linkedorganopolysiloxane elastomers useful in the present invention andprocesses for making them are further described in U.S. Pat. No.4,970,252 to Sakuta et al., issued Nov. 13, 1990; U.S. Pat. No.5,760,116 to Kilgour et al., issued Jun. 2, 1998; U.S. Pat. No.5,654,362 to Schulz, Jr. et al. issued Aug. 5, 1997; and Japanese PatentApplication JP 61-18708, assigned to Pola Kasei Kogyo KK, each of whichare herein incorporated by reference in its entirety.

The compositions of the present invention comprise a combination ofemulsifying and non-emulsifying crosslinked organopolysiloxaneelastomer. The term “non-emulsifying,” as used herein, definescrosslinked organopolysiloxane elastomer from which polyoxyalkyleneunits are absent. The term “emulsifying,” as used herein, meanscrosslinked organopolysiloxane elastomer having at least onepolyoxyalkylene unit. Emulsifying crosslinked organopolysiloxaneelastomer can notably be chosen from the crosslinked polymers describedin U.S. Pat. No. 5,412,004 (issued May 2, 1995); 5,837,793 (issued Nov.17, 1998); and 5,811,487 (issued Sep. 22, 1998), all of which are hereinincorporated by reference in their entirety.

Particularly useful emulsifying elastomers are polyoxyalkylene modifiedelastomers formed from divinyl compounds, particularly siloxane polymerswith at least two free vinyl groups, reacting with Si—H linkages on apolysiloxane backbone. Preferably, the elastomers are dimethylpolysiloxanes crosslinked by Si—H sites on a molecularly spherical MQresin.

The non-emulsifying cross-linked organopolysiloxane elastomers of thepresent invention are preferably further processed by subjecting them toa high shear (approximately 5,000 psi) treatment in the presence of asolvent for the siloxane elastomer via a Sonolator at less than 10passes. Sonolation achieves a resultant composition with elastomeraverage particle size ranging from at least 20 (or about 20) microns toabout 200 microns, preferably from about 30 to about 150 microns, morepreferably from 40 (or about 40) to about 95 microns and most preferablyfrom about 50 microns to about 90 microns as measured by the HoribaLA-910 (described below). As used herein, the term “particle size” ofthe elastomer represents the elastomer particle size in its swelledstate. By “swelled,” as used herein, means that the elastomer particleshave extended beyond their normal size and shape by virtue of theirabsorption of the solvent compound. Viscosity is best when rangingbetween above 20,000 (or above about 20,000) and about 6,000,000,preferably from about 25,000 to about 4,000,000, more preferably fromabout 30,000 to about 3,000,000, most preferably from about 40,000 toabout 2,000,000, optimally about 60,000 to about 1,500,000 cps at 25° C.as measured by a Brookfield LV Viscometer (size 4 bar, 60 rpm, 0.3sec.).

Without being limited by theory, the present inventors believe thatcompositions incorporating non-emulsifying elastomer/solvent gels wherethe non-emulsifying cross-linked organopolysiloxane elastomer has anaverage particle size greater than 10 microns (or greater than about 10microns) and/or viscosities greater than 20,000 cps provide films havingimproved smoothness as well as improved uniformity and evenness ofparticle (e.g., pigments) distribution within the film (i.e., solidparticles remain distributed within and throughout the film as opposedto such particles protruding from the film into and/or across thefilm/air interface).

Preferably, the non-emulsifying cross-linked organopolysiloxaneelastomers do not undergo recycled processing. Without being limited bytheory, recycled processing produces broad particle size distributionscomprising particles larger or smaller than that necessary to achievethe skin feel benefits of the present invention. Specifically, gel ballsoften result from silicone elastomer particles larger than 200 micronswhile elastomer particles smaller than 10 microns reduce skin feel andviscosity benefits. Such particle size distributions result from afailure to ensure that all of the elastomer particle materialsexperience the same shear throughout the process. Typically, withrecycling, only a portion of the particles experience shear before thesesheared particles are returned to the process starting point andcombined with the remaining un-sheared particles. Similarly, the nextcycle begins with only a portion of this particle mixture experiencingbefore the newly sheared mixture particles are returned to the processstarting point and combined with the remaining un-sheared particlemixture. Importantly, even after considerable recycling, some of theparticles never actually experience shear while others experience a highdegree of shear. The result is a particle size range, which encompassesparticles both larger and smaller than those necessary to achieve thepresent invention.

In contrast, discrete pass processing, as alluded to above, ensures thatall the particles experience shear as well as the same amount of shearwith each run or pass. More specifically, no run or pass is completeduntil all the particles have experienced the same shear force.Consequently, the particle size distribution is narrower than thatproduced by “recycling” with respect to specific particle sizes. Thisresults in a better balance between gel ball formation and viscosity aswell as skin feel and viscosity.

The non-emulsifying crosslinked organopolysiloxane elastomer is presentin the compositions of the present invention at concentrations of fromabout 0.1 to about 15%, optimally from about 1 to about 10%, mostpreferably from about 3 to about 8% by weight.

Solvent for the Non-emulsifying and Emulsifying Crosslinked SiloxaneElastomer

The compositions of the present invention comprise a solvent for thecrosslinked organopolysiloxane elastomer described above. The solvent,when combined with the cross-linked organopolysiloxane elastomerparticles of the present invention, serves to suspend and swell theelastomer particles to provide an elastic, gel-like network or matrix.The solvent for the cross-linked siloxane elastomer is liquid underambient conditions, and preferably has a low viscosity to provide forimproved spreading on the skin.

Concentrations of the solvent in the cosmetic compositions of thepresent invention will vary primarily with the type and amount ofsolvent and the cross-linked siloxane elastomer employed. Preferredconcentrations of the solvent are from about 10% to about 90%,preferably from about 20% to about 80%, more preferably from about 30%to about 70%, by weight of the composition.

The solvent for the cross-linked siloxane elastomer comprises one ormore liquid carriers suitable for topical application to human skin.These liquid carriers may be organic, silicone-containing orfluorine-containing, volatile or non-volatile, polar or non-polar,provided that the liquid carrier forms a solution or other homogenousliquid or liquid dispersion with the selected cross-linked siloxaneelastomer at the selected siloxane elastomer concentration at atemperature of from about 28° C. to about 250° C., preferably from about28° C. to about 100° C., preferably from about 28° C. to about 78° C.The solvent for the cross-linked siloxane elastomer preferably has asolubility parameter of from about 3 to about 13 (cal/cm³)^(0.5), morepreferably from about 5 to about 11 (cal/cm³)^(0.5), most preferablyfrom about 5 to about 9 (cal/cm³)^(0.5). Solubility parameters for theliquid carriers or other materials, and means for determining suchparameters, are well known in the chemical arts. A description ofsolubility parameters and means for determining them are described by C.D. Vaughan, “Solubility Effects in Product, Package, Penetration andPreservation” 103 Cosmetics and Toiletries 47-69, October 1988; and C.D. Vaughan, “Using Solubility Parameters in Cosmetics Formulation”, 36J. Soc. Cosmetic Chemists 319-333, September/October, 1988, whicharticles are incorporated herein by reference.

The solvent preferably includes volatile, non-polar oils; non-volatile,relatively polar oils; non-volatile, non-polar oils; and non-volatileparaffinic hydrocarbon oils; each discussed more fully hereinafter. Theterm “non-volatile” as used herein refers to materials which exhibit avapor pressure of no more than about 0.2 mm Hg at 25° C. at oneatmosphere and/or to materials that have a boiling point at oneatmosphere of at least about 300° C. The term “volatile” as used hereinrefers to all materials that are not “non-volatile” as previouslydefined herein. The phrase “relatively polar” as used herein means morepolar than another material in terms of solubility parameter; i.e., thehigher the solubility parameter the more polar the liquid. The term“non-polar” typically means that the material has a solubility parameterbelow about 6.5 (cal/cm³)^(0.5.)

1. Non-polar, Volatile Oils

The non-polar, volatile oil tends to impart highly desirable aestheticproperties to the compositions of the present invention. Consequently,the non-polar, volatile oils are preferably utilized at a fairly highlevel. Non-polar, volatile oils particularly useful in the presentinvention are selected from the group consisting of silicone oils;hydrocarbons; and mixtures thereof. Such non-polar, volatile oils aredisclosed, for example, in Cosmetics, Science, and Technology, Vol. 1,27-104 edited by Balsam and Sagarin, 1972. The non-polar, volatile oilsuseful in the present invention may be either saturated or unsaturated,have an aliphatic character and be straight or branched chained orcontain alicyclic or aromatic rings. Examples of preferred non-polar,volatile hydrocarbons include polydecanes such as isododecane andisodecane (e.g., Permethyl-99A which is available from Presperse Inc.)and the C7-C8 through C12-C15 isoparaffins (such as the Isopar Seriesavailable from Exxon Chemicals). Non-polar, volatile liquid siliconeoils are disclosed in U.S. Pat.

Silicones), GE7207 and 7158 (commercially available from General Electric Co.); andSWS-03314 (commercially available from SWS Silicones Corp.).

2. Relatively Polar, Non-volatile Oils

The non-volatile oil is “relatively polar” as compared to the non-polar,volatile oil discussed above. Therefore, the non-volatile co-solvent ismore polar (i.e., has a higher solubility parameter) than at least oneof the non-polar, volatile oils. Relatively polar, non-volatile oilspotentially useful in the present invention are disclosed, for example,in Cosmetics, Science, and Technology, Vol. 1, 27-104 edited by Balsamand Sagarin, 1972; U.S. Pat. No. 4,202,879 issued to Shelton on May 13,1980; and U.S. Pat. No. 4,816,261 issued to Luebbe et al. on Mar. 28,1989, all of which are herein incorporated by reference in theirentirety. Relatively polar, non-volatile oils useful in the presentinvention are preferably selected from the group consisting of siliconeoils; hydrocarbon oils; fatty alcohols; fatty acids; esters of mono anddibasic carboxylic acids with mono and polyhydric alcohols;polyoxyethylenes; polyoxypropylenes; mixtures of polyoxyethylene andpolyoxypropylene ethers of fatty alcohols; and mixtures thereof. Therelatively polar, non-volatile co-solvents useful in the presentinvention may be either saturated or unsaturated, have an aliphaticcharacter and be straight or branched chained or contain alicyclic oraromatic rings. More preferably, the relatively polar, non-volatileliquid co-solvent are selected from the group consisting of fattyalcohols having from about 12-26 carbon atoms; fatty acids having fromabout 12-26 carbon atoms; esters of monobasic carboxylic acids andalcohols having from about 14-30 carbon atoms; esters of dibasiccarboxylic acids and alcohols having from about 10-30 carbon atoms;esters of polyhydric alcohols and carboxylic acids having from about5-26 carbon atoms; ethoxylated, propoxylated, and mixtures ofethoxylated and propoxylated ethers of fatty alcohols with from about12-26 carbon atoms and a degree of ethoxylation and propoxylation ofbelow about 50; and mixtures thereof. More preferred are propoxylatedethers of C14-C18 fatty alcohols having a degree of propoxylation belowabout 50, esters of C2-C8 alcohols and C12-C26 carboxylic acids (e.g.ethyl myristate, isopropyl palmitate), esters of C12-C26 alcohols andbenzoic acid (e.g. Finsolv TN supplied by Finetex), diesters of C2-C8alcohols and adipic, sebacic, and phthalic acids (e.g., diisopropylsebacate, diisopropyl adipate, di-n-butyl phthalate), polyhydric alcoholesters of C6-C26 carboxylic acids (e.g., propylene glycoldicaprate/dicaprylate, propylene glycol isostearate); and mixturesthereof. Even more preferred are branched-chain aliphatic fatty alcoholshaving from about 12-26 carbon atoms. Even more preferred are isocetylalcohol, octyldecanol, octyldodecanol and undecylpentadecanol; and mostpreferred is octyldodecanol. Such preferred aliphatic fatty alcohols areparticularly useful in combination with the volatile liquid siliconeoils discussed herein to adjust the average solubility of the solvent.

3. Non-polar, Non-volatile Oils

In addition to the liquids discussed above, the solvent for thecross-linked siloxane elastomer may optionally include non-volatile,non-polar oils.

OPTIONAL INGREDIENTS

Shine Control Agents

Cosmetic products that improve and/or regulate the condition of theshiny appearance of skin are increasingly popular with consumers and arereferred to herein as “shine control agents”. Shine control agents maybe included in the compositions of the present invention.

A frequent, undesirable condition is “oily skin”, which results from theexcessive amount of sebum and sweat that is excreted onto the skin.Sebum is an oily mixture, composed principally of squalene,triglycerides, fatty acids and wax esters. Sebum is produced in thesebaceous glands of the skin. Oily skin is associated with a shiny,undesirable appearance and disagreeable tactile sensation. Sweat ispredominantly water with trace quantities of dissolved inorganic saltssuch as sodium chloride and potassium chloride.

Typically, shine control agents are porous in nature. These agents, whenapplied to the skin provide a reservoir to absorb excess moisture intothe pores, hence reducing the visible quantity of moisture on the skin.

Without being limited by theory, it is believed that it is preferable tocombine the use of effective porous, absorbent materials withnon-absorbing spherical materials. The latter emphasizes the effect ofdiffuse reflection over problematic specular reflection, causing anoptical modification to the skin and hence a reduction in the shinyappearance of the skin. The combination of absorber and non-absorbingspherical particles is preferable because it allows development of aproduct with optimum shine control as well as providing a product withthe best tactile sensory performance.

Suitable shine control agents include, but are not limited to, silicas,magnesium aluminum silicates, talc, sericite and various organiccopolymers. Particularly effective shine control agents includesilicates or carbonates that are formed by reaction of a carbonate orsilicate with the alkali (IA) metals, alkaline earth (IIA) metals, ortransition metals, and silicas (silicon dioxide). Preferred shinecontrol agents are selected from the group consisting of calciumsilicates, amorphous silicas, calcium carbonates, magnesium carbonates,zinc carbonates, and combinations thereof. Some specific examples of thesilicates and carbonates useful in this present invention are more fullyexplained in Van Nostrand Reinhold's Encyclopedia of Chemistry, 4^(th)Ed. pp155, 169, 556, and 849 (1984).

Synthetic versions of the shine control agents, particularly silicates,are preferred. Examples of synthetic silicates useful in the presentinvention are Hubersorb 250® or Hubersorb 600®, available from J MHuber.

Shine control agents that primarily comprise silicas are preferred overthose materials comprising mainly silicates and/or carbonates when usedfor moisture and shine control. Most preferred silicas are in the formof microspheres and/or ellipsoids, as they have been found to contributegood skin feel characteristics in addition to efficient moistureabsorption. Silica ellipsoids useful in the present invention areavailable from DuPont as ZELEC Sil and Kobo as Silica Shells. Silicamicrospheres are available from Kobo as MSS-500, MSS500/3, MSS-500H,MSS500/3N, MSS-500N and MSS 500/3N; Presperse as Spheron L1500, SpheronP1500. Fumed versions of silica can also be used with Aerosil fromDegussa and Cab-O-Sil from Cabot both being particularly useful.

Amongst the silicate series, magnesium aluminum silicates are useful, inparticular Sebumase, available from Miyoshi Kasei.

When silicas, particularly silica ellipsoids and silica microspheres areintended to be the main means for moisture absorption, it is preferredthat the absorbent powder comprise from about 1% to about 40%; morepreferably from about 1% to about 25%, and most preferably from about 2%to about 10%, by weight of the composition, of silicas.

Solidifying Agent

The cosmetic compositions of this invention can contain one or morematerials, herein singly or collectively referred to as a “solidifyingagent”, that are effective to solidify the particular liquid basematerials to be used in a cosmetic composition. (As used herein, theterm “solidify” refers to the physical and/or chemical alteration of theliquid base material so as to form a solid or semi-solid at ambientconditions, i.e., to form a final composition that has a stable physicalstructure and is deposited on the skin during normal use conditions.) Asis appreciated by those skilled in the art, the selection of theparticular solidifying agent for use in the cosmetic compositions willdepend upon the particular type of composition desired, i.e., gel orwax-based, the desired rheology, the liquid base material used and theother materials to be used in the composition. The solidifying agent ispreferably present at a concentration of from about 0 to about 90%, morepreferably from about 1 to about 50%, even more preferably from about 5%to about 40%, most preferably from about 1% to about 15%.

Preferably, the compositions of the present invention have a hardnessvalue as measured using a TA-XT2i Texture Analyzer (described below) ofup to about 25 gram-force, more preferably from about 0.5 to about 20gram-force, most preferably from about 1 to about 15, optimally fromabout 1 to about 10 gram-force. Without being limited by theory, it isbelieved that compositions having stick hardness values above 25gram-force tend to interfere with the formation of the film structureprovided by the polysiloxane elastomer, thus, preventing the smoothnessas well as improved uniformity and evenness of particle distributionwithin the film. This, in turn, negatively affects the sensory benefitsof the cross-linked polysiloxane elastomer component.

Colorant

Certain embodiments of the present invention contain from about 0% toabout 30%, preferably from about 1% to about 20%, more preferably fromabout 2% to about 15% and most preferably from about 5% to about 15%, ofa colorant, on an anhydrous pigment weight basis. These are usuallyaluminum, barium or calcium salts or lakes. Preferably, dyes are presentat from about 0% to about 3% and pearls and the like from 0% to about10%.

Colorants useful herein are all inorganic and organic colors/pigmentssuitable for use in cosmetic compositions. When used, pigments aretypically dispersed in emollients for the good dispersion of thepigments when incorporated into lip compositions of the presentinvention, thus providing an even distribution of color. Lakes areeither a pigment that is extended or reduced with a solid diluent or anorganic pigment that is prepared by the precipitation of a water-solubledye on an adsorptive surface, which usually is aluminum hydrate. Thereis uncertainty in some instances as to whether the soluble dyeprecipitates on the surface of the aluminum hydrate to yield a dyedinorganic pigment or whether it merely precipitates in the presence ofthe substrate. A lake also forms from precipitation of an insoluble saltfrom an acid or basic dye. Calcium and barium lakes are also usedherein.

Lakes suitable for use in the present invention include Red 3 AluminumLake, Red 21 Aluminum Lake, Red 27 Aluminum Lake, Red 28 Aluminum Lake,Red 33 Aluminum Lake, Yellow 5 Aluminum Lake, Yellow 6 Aluminum Lake,Yellow 10 Aluminum Lake, Orange 5 Aluminum Lake and Blue 1 AluminumLake, Red 6 Barium Lake, Red 7 Calcium Lake.

Other useful powdersare disclosed in U.S. Pat. No. 5,688,831, to El-Nokaly et al., issuedNov. 18, 1997, herein incorporated by reference in its entirety. Thesepigments and powders can be used independently or in combination.

Also useful herein are pigment and/or dye encapsulates suchnanocolorants from BASF and multi-layer interference pigments such asSicopearls from BASF.

It is preferred that the pigments/powders are surface treated to provideadded stability of color and ease of formulation. Hydrophobicallytreated pigments are more preferred, because they may be more easilydispersed in the solvent/oil phase. In addition, it may be useful totreat the pigments with a material that is compatible with a siliconephase. Particularly useful hydrophobic pigment treatments for use inwater-in-silicone emulsions include polysiloxane treatments such asthose disclosed in U.S. Pat. No. 5,143,722, incorporated herein byreference in its entirety. Also preferred are pigment/powders having aprimary average particle size of from about 5 nm to about 100,000 nm,more preferably from about 50 nm to about 5,000 nm, most preferably fromabout 100 nm to about 1000 nm. Mixtures of the same or differentpigment/powder having different particle sizes are also useful herein(e.g., incorporating a TiO2 having a primary particle size of from about100 nm to about 400 nm with a TiO2 having a primary particle size offrom about 10 nm to about 50 nm).

Dispersants may also be used in conjunction with the colors and pigmentsof the present invention. Examples of suitable dispersants include, butare not limited to, those described in U.S. Pat. No. 5,688,493, hereinincorporated by reference in its entirety.

Preservatives Suitable traditional preservatives for compositions ofthis invention are alkyl esters of para-hydroxybenzoic acid. Otherpreservatives that have more recently come into use include hydantoinderivatives such as 1,3-bis(hydroxymethyl)-5,5-dimethylhydantoin,propionate salts, and a variety of quaternary ammonium compounds such asbenzalkonium chloride, quaternium 15 (Dowicil 200), benzethoniumChloride, and methylbenzethonium chloride. Cosmetic chemists arefamiliar with appropriate preservatives and routinely choose them tosatisfy the preservative challenge test and to provide productstability.

Analytical Test Methods

Determination of Particle Size

Samples are prepared placing approximately 1 gram of the cross-linkedelastomer (gel) in a small bottle with approximately 30 grams of a 1:1isopropyl alcohol:dimethicone (DC 245) solution (IPA:DC245). The 1:1IPA:DC245 solution is passed through a 0.2 μm syringe filter to removeforeign particulates (e.g., dust). The sample is then mixed (to disperseelastomer) using a Glass-Col Tissue Culture Rotator set at 70% forapproximately 5 days.

The samples were, next, measured using a Horiba LA-910 equipped with afraction cell holder and a magnetic stir bar. For a blank, a separatesample was prepared containing only the 30 grams 1:1 IPA:DC245. Beforemeasurement, 10 ml aliquots of the prepared samples were placed in asmall vial and allowed to settle for 30 minutes (to separate out largeagglomerates). Stirring was used during measurement and the samplingtime was set at 25 sec., the data were reported on a Volume basis usinga relative refractive index of 1.06-0.00 i. Samples are further dilutedwith 1:1 IPA:DC245 as necessary to achieve concentrations within theworking range for the Horiba LA-910. More detailed instructions can befound in the Operator's Manuel for the Horiba LA 910, hereinincorporated by reference. The process is additionally described in U.S.Pat. No. 5,998,542 and U.S. Pat. No. 5,929,162, both of which are hereinincorporated by reference in their entirety
